First video, once you skip the first 17 minutes which have nothing at all to do with Starlink, is based on two premises: 1. That on-orbit and orbit-to-surface bandwidth will never increase, and 2. That the prototype receivers are the final receivers. 2 has already been proven false with the second generation receiver, and there's no reason to assume that, with so much of the fleet getting replaced every decade, that the network bandwidth will be forever so limited. I don't think laser link tracking is terribly difficult on-orbit, particularly among satellites that share one. It's also considerably slower than stated, falling at 7.2-7.9km/s, not 20,000km/s.
